DRIVING MECHANISM FOR AIRSHIPS.

Specification ot Letters Patent.

Application filed July 2, 1909.

Patented 'Mal'. 21, 191 1.

serial No. 505,694.

To alt whom it may concern:

lle it known that' l. .loin-wx Stiiifrrl-z. a subject of the Kingof Prussia. residing' at 4T" .liischltenthalerweg. liangfuhl.'` near Danzig', (termauy. have invented certain new aud useful lmlu'oveuunts in 'Driving Mechanisms for .\irships: and l do hereby declare the following` to be a full. clear, and exact description of the invention. such as will enable others skilled in the art to which it a ppertains to malte and use the lsaine. rel"- erence beingl had to the accompanying drawings, and to letters or figures't'if reference marked thereon. which 'form a part of this specification.

)ly invention rel-.ttes to 'driving mechanism for air-ships, and has for its object to provide a mechanism for driving a plurality of shafts iu unison` by means of a motor on each shaft, together with means for driving' the shafts either in the same direction or in opposite diret'rtions, from any one of the motors, in case any of the motors become inoperative from any reason whatever, and details of construct-ion hereinafter more. particularly described and claimed.

Referring to the drawings, in which like parts are similarly designated-Figure' l shows a plan view of an air-ship car with the balloon shown in dotted lines'. Fig. 3 is an enlarged detail view showing the mechanism for driving `two parallel shafts.

il, "2 are the driving shafts for the. propellcrs l. each of which shafts is driven by a pertaining motor M1 and M2 respectively. The two shafts W1 and lV'2 are normally driven by the motors .M1 and M2 in opposite- Ibelt pulleys l and and the shaft lV: carries two fixed belt pulleys l and l0. The belt pulley l is belted by a crossed belt to the part4 L). of the. belt. pulley 12 of' the interiu'ediafc sha-ft lV". pulley l2 is belted by an uncrossed belt to the-belt pulley l on the shaft W1: thc loose belt pulley l1 is'adjaocntto the pulley 12. The belt pulley 5 is connected by a crossed belt to loose belt pulley 6 and the loose belt pulley 7 is connected by an unc-ressent belt to the belt. pulley 10. The' belt pulley, 8 secured to the shaft lV, lies between the loose belt pulleys 6 and 7 and the belt pulley The part 3 of `the belt' 0. also fixed on shaft 73, lies adjacent the loose belt. pulley T.

K1 and Kg are couplings for the shaft W1, and K is a coupling for the shaft W2. both of these shafts being in sections, and coupled' together by said couplings. Should it be desired to reverse the rotation of the propellers I), the couplings K2 und K3 are disengaged, and the crossed belt is shifted from loose pulley to fixed pulley '8, and the uncrossed belt is shifted 'from the loose pulley 7 tofixed pulley 9. The two motors M1 and M2 thereby drive the pulleys l0 and :i to uniformly drive the shaft W which drives the propeller shaft sections rearwardly of the couplings K2 and K3 by means of the part 2 of the pulley l2 and the pulley l, on the one hand, and by means of the part 'of the pulley l2 and pulley Lon the other hand. one of the screws be reversed While the other is not reversed, then7 for example, the con pling K3 is disengaged and 'the uncrossed belt is shifted from pulley 3 to loose pulley 11 and the crossed belt is shifted from pnlL ley 6 to the fixed pulley S. Thus it. Will be seen that the entire machine is under absolute control, by controlling,r the shifting.; of

Should it be desired that two screw-propeller shafts and a motor to drive each of them. said shafts composed of sections and means to couple 'and uncouple said sections: of a third shaft betweenpthe propeller shafts, a pair of belt pulleys on each propeller shaft and three loose and three fixed pulleys on the intermediate shaft. a crossed and an uncrossed belt connec-tion between each motor shaft and the intermediate shaft, whereby each motor .may drive bothshafts in the saine direction or in opposite directions. .Y

2. In an air-ship, the combination with the screwpropeller shafts and a. motor to drive each of them, said shafts composed of sections, and means to couple the sections; of a third shaft between the propeller shafts. therear section of one propellershaft belted by an uncrossed belt` to the intermediate shaft and the other section of said propeller shaft'belted by a crossed belt to the interthe t'l'xed pulleys and one ofthe loose pulleys on the intermediate .shaft being belted to different sections of one of the propeller shafts by an uncrossed belt-and a cross belt respectively, said fined pulley being belted by a. cross-belt to a pulley 011 one section of the other propellerl shaft', and another one of said loose pulleys on the intermediate shaft being belted by an uncrossed belt to another section othe last named propeller shaft, whereby each motor or both motors may drive both shafts in the same direction forward or rearward or in opposite directions.
